Does Westbury flood?
What the Environment Agency's rivers-and-sea flood-risk data says about Westbury
Ordnance Survey places 36 postcodes in Westbury in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea). Each postcode is counted once, under the worst band any of its properties reaches; together they hold 298 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 12 | 63 | 58 |
| Medium | 8 | 73 | 68 |
| Low | 16 | 162 | 149 |
| Very low | 0 | 0 | 0 |
| All bands | 36 | 298 | 275 |
This dataset covers flooding from rivers and the sea only — one of five flood sources. Surface water, groundwater, sewers and reservoirs are assessed separately, so a postcode missing from it is not proof that a place cannot flood. The band describes the land around properties (allowing for defences), not any single address and not today's conditions.
